Abstract
The invention discloses a novel waterproof synthetic leather sizing agent and a preparation method thereof. The novel waterproof synthetic leather sizing agent is prepared from the following raw materials in parts by weight: 110-120 parts of waterborne polyurethane resin, 10-12 parts of trimellitic anhydride, 0.4-0.5 part of methyl tetrahydrophthalic anhydride, 1.5-1.6 parts of sodium dodecyl sulfate, 1-2 parts of gelatin, 0.5-0.8 part of smoked rubber sheet, 43-45 parts of barium sulfate powder, 6-8 parts of peanut leaf, 3.5-4.5 parts of a silane coupling agent G-570 and 25-30 parts of tetrahydrofuran. The prepared novel waterproof synthetic leather sizing agent is high in tenacity, excellent in waterproofness, bright in appearance color and soft in hand feel. The gelatin and barium sulfate powder in the formula can effectively improve the waterproofness and leakage resistance of the sizing agent and reduce cracks caused by empty bulges; in addition, the viscidity of the peanut leaf can be improved when the peanut leaf is modified to enhance the viscidity of the sizing agent and improve the stable performance of the sizing agent.
Description
Technical field
The present invention relates to a kind of slurry used for artificial leather, be specifically related to a kind of new waterproof type synthetic leather slurry and preparation method thereof.
Background technology
Synthetic Leather has that gloss is soft, nature, and soft, kishke feel is strong, and flex endurant, the excellent feature such as anti-aging, be the ideal substitute of natural leather, be widely used in the industries such as clothes, shoemaking, case and bag, furniture; But Synthetic Leather is in the market too large with natural leather gap in poisture-penetrability, ABRASION RESISTANCE, the Synthetic Leather goods of water vapour permeability difference can make us feeling sultry, clammy, for these shortcomings, performance at present mainly through changing Synthetic Leather slurry is improved, but the technique changing Synthetic Leather slurry poisture-penetrability and ABRASION RESISTANCE is in the market more complicated, cost is higher, and effect is also not too obvious.
Summary of the invention
The object of the present invention is to provide a kind of new waterproof type synthetic leather slurry and preparation method thereof.
The present invention adopts following technical scheme:
New waterproof type synthetic leather slurry, the weight portion of its constitutive material is: waterborne polyurethane resin 110-120, trimellitic anhydride 10-12, methyl tetrahydro phthalic anhydride 0.4-0.5, lauryl sodium sulfate 1.5-1.6, natural plant gum 1-2, rubber smoked sheet 0.5-0.8, barium sulfate powder 43-45, fallen flowers leave 6-8, silane coupler G-570 3.5-4.5 and oxolane 25-30.
New waterproof type synthetic leather slurry, the weight portion of its constitutive material is: waterborne polyurethane resin 115, trimellitic anhydride 11, methyl tetrahydro phthalic anhydride 0.45, lauryl sodium sulfate 1.5, natural plant gum 1.5, rubber smoked sheet 0.6, barium sulfate powder 44, fallen flowers leave 7, silane coupler G-570 4 and oxolane 28.
The preparation method of new waterproof type synthetic leather slurry, comprises the following steps:
(1) modification of fallen flowers leave: take fallen flowers leave by the weight portion of constitutive material, fallen flowers leave is pulverized, dries, add little water and appropriate hydrogen peroxide, soak and with the sodium bicarbonate solution of 0.1mol/L, pH value is adjusted to 7-8 after 30-40 minute, add 3-4% nano silicon and the 2-4% gelatin of peanut leaf quality again, stirring reaction 1-4 hour at 50-80 DEG C of temperature, in 105-110 DEG C of baking oven, 4-5 hour is dried again after suction filtration, washing, obtain modification fallen flowers leave, for subsequent use;
(2) add in reactor by the modification fallen flowers leave of step (1), then add oxolane and be uniformly mixed, ball milling dispersion 15-20h after first ultrasonic disperse 15-20min, then adds other residue constitutive material, stirs; Slurry is obtained again through ultrasonic disperse 25-35min and ball milling dispersion 4-6h.
By obtained synthetic leather slurry with 150-180g/m
2blade coating amount be applied to release liners surface, fit together with synthetic leather base cloth again after drying, upper paste, under 100-120 DEG C of condition, dry 5-6 minute, then under 80-100 DEG C of condition, solidify 18-20 hour.
Beneficial effect of the present invention:
The slurry toughness that the present invention obtains is strong, and water resistance is good, bright-colored in appearance, soft, and the natural plant gum in formula and barium sulfate powder effectively improve waterproof, anti-leakage, the minimizing hollowing cracking of synthetic leather slurry; And the present invention is by the modification to fallen flowers leave, can improve the viscosity of fallen flowers leave, strengthen the toughness of slurry, improve the stable performance of slurry.
